We have a rubber mooring compensator in our single line snubber and a pair in our bridle. They add stretch without length keeping the hook off the bottom in calm periods and thus keeping it attached to the chain. The photo is in Marsh Harbour. The line is nylon of dubious origin, maybe 3/8' or maybe 1/2".
